Dublin, Wicklow and Wexford Railway (DW&WR) 55 to 58 were 4-4-0 locomotives built from 1895 at Vulcan Foundry for express passenger duties on the Dublin—Wexford mainline.
They were to remain the DW&WR's and subsequent Dublin and South Eastern Railway's leading express passenger locomotive until the arrival of Nos.
These 4-4-0 locomotives built from 1895 at Vulcan Foundry and named Rathdown, Rathmines, Rathnew and Rathdrum.
[1] In their initial form they were poor steamers, the suggestion being the locomotive superintendent Grierson had specified larger cylinders on a previous design for an English railway without balancing this with an increased boiler.
[1] These engines took over the express passenger trains from the smaller 2-4-0 type on the DW&WR's Dublin—Wexford mainline route.
